| Abstract: | The hemagglutinating activity and serological properties of three strains of rabbit hemorrhagic disease virus, Chinese, Korean and Shizuoka, which was first isolated in Japan, were examined by hemagglutination (HA) and cross hemagglutination inhibition (HI) test with human erythrocytes. Similar results were observed between the Chinese and Korean strains, both of which gave positive HA at 4 degrees C with O, A, B and AB, and at 22 degrees C with B and AB blood groups. In the Shizuoka strain, positive HA was observed at 4 degrees C with O, A, B and AB, at 22 degrees C with A, B And AB, and at 37 degrees C with B blood group. In experimentally infected rabbits, HI antibody in these animals showed a titer of 16,384 or 32,768 at 4 weeks after inoculation. No serological difference was observed in three strains by cross HI test. |
